I was a huge ELP Fan.
This site “Voltage Control Lab” Talks about Keith Emerson, the synthesizers he used and his unfortunate suicide. Like Rick Wakeman, Emerson was one of the best.

Im very glad to have seen both of those guys in their prime in the mid-70s. Saw ELP when they were touring behind Brain Salad Surgery.
